Swim It is a virtual event where we are challenging you to swim 21 miles, the equivalent length of The Channel, throughout June and July. Unlike other events, you get to choose where, when and how you swim the distance.
When you sign up, you’ll receive a personalised JustGiving fundraising page where you can log your miles, share progress, earn virtual badges and collect donations from your supporters.
To thank you for your hard work, we have some exclusive merch up for grabs so you can really look the part and Swim It in style. T&C's apply.

What is Gift Aid and can I add it to my donation?
Gift Aid is a great opportunity for donors to make their voluntary donations to Macmillan worth 25% more – without spending an extra penny. It enables charities like us to claim the basic tax that donors have paid on their donations back from HM Revenue & Customs (HMRC).
If every supporter agreed to Gift Aid it would raise hundreds of thousands of pounds more to support people affected by cancer.
To be eligible to add Gift Aid to your donation you must be a UK taxpayer and you must have paid or will pay an amount of Income Tax and/or Capital Gains Tax for the current tax year, that is at least equal to the amount of tax that all the charities and Community Amateur Sports Clubs (CASCs) that you donate to will reclaim on my gifts for the current tax year. Other taxes such as VAT and Council Tax do not qualify. The charity will reclaim 25p of tax on every £1 that you have given.
How can I let you know I changed my mind about hearing from Macmillan?
If you change your mind about hearing from us, you can stop receiving our updates at any time by emailing fundraising@macmillan.org.uk or calling 0300 1000 200. Please see our privacy statement for more information.
